Moist and decadent vegan spice cake layered with a vegan cream cheese frosting! This holiday cake is perfect for all ages and naturally gluten free, Paleo, and dairy free!


  • 2 cups sweet potato, cooked + mashed
  • 3 cups cassava flour
  • 1/2 cup maple syrup 
  • 1 tsp baking soda
  • 2 cups coconut milk + 1 tsp apple cider vinegar
  • 1 tbsp cinnamon
  • 2 tsp ginger
  • 1 tsp allspice
  • 1 tsp cardamom
  • 1 tsp vanilla extract
  • 3 tbsp ground flaxseed mixed with 1/3 cup water

Vegan Cream Cheese Frosting:

  • 1 cup vegan butter, softened but still cold
  • 1 cup vegan cream cheese, softened but still cold
  • 3 cups powdered sugar (for Paleo, use 3 cups powdered coconut sugar)


  1. Preheat the oven to 350F and grease two 8″ cake pans with coconut or olive oil.
  2. In a large bowl, whisk together the cassava flour, baking soda, and spices. Set aside.
  3. In a medium bowl, use a hand mixer to combine the mashed sweet potatoes, maple syrup, coconut milk with apple cider vinegar, and ground flaxseed mixture.
  4. Pour the wet ingredients into dry and mix thoroughly.
  5. Divide the batter amongst the two cake pans evenly and bake for 32-36 minutes, or until the toothpick comes out clean.
  6. Remove from the oven and let cool for 10 min before removing from the pan.
  7. To make the frosting: use a hand mixer or stand mixer to beat together the vegan butter and cream cheese until fluffy. Sift in the powdered sugar in increments until well combined.
  8. To assemble: level the cakes if needed then spread a thick layer of frosting on top of one cake. Place the second cake crumb side down and continue to frost the rest of the cake.
  9. Serve and enjoy!
